Carnetix CNX-P1900 Ver. 2.2 (see version change log below)
See the P1900 Product Brief here.
The CNX-P1900 is a 140 watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs......including the Mac Mini and Pentium P4-based systems!
The P1900 provides two outputs. The primary output is jumper selectable for 18V, 19V, or 20V operation and can provide up to 6.32 amps (125 Watts @ 20V ). The secondary output is jumper selectable to provide either +12V to power your LCD screen (or 13.5V or experimental purposes), or +5V to power USB devices (such as the Audigy 2NX sound USB sound card) with up to 3 amps (15 Watts). The P1900 can accept battery input as low as 7 volts under full load (140 watts) during cranking while providing a well-regulated output so that your CarPC does not crash.
The P1900 includes all of the sophisticated features of its predecessors (P1260 and P1280) such as Startup/Shutdown controller, Pulse Start (remotely start the P1900 with door locks, car alarm, or wireless device), and DelayON (prevents speaker "thump" during booting). The P1900 fully and safely supports "Standby" mode and will automatically shut itself down (by detecting excess current drain) if the CarPC fails to properly go into Standby mode.
The P1900 is also designed to power larger systems that demand higher power, such as P4-based motherboards (ie Insight P4 ITX) with full sized hard drives. The P1900 is fully compatible with the Travla C137 (90 watt and 120 models), the C138 (90 watt and 120 watt models) as well as the newer C158 (90 watt and 120 watt models) cases. In fact, the most cost effective P4 CarPC system can be built using the Travla C137, C138, or C158-120 and the Insight P4 ITX motherboard.
In addition, the P1900 can be used with the Mac mini, Sumicom, Xenarc, and Cappucino models that require an 18v, 19v, or 20v power source.
